Supplement with omega-3 fatty acids, vitamin E and carotenoids increases working memory of people over 65
If people over 65 take a supplement with DHA, EPA, vitamin E and a number of carotenoids, their working memory increases. This means that when they are performing mental tasks or making decisions, they can hold more things in their minds at once and are less likely to lose the thread of their thoughts.
Researchers from the Irish Waterford Institute of Technology divided fifty healthy people over 65 into 2 groups. For 2 years, one group took a placebo while another group took a supplement containing DHA, EPA, vitamin E, lutein, zeaxanthin and meso-zeaxanthin.

The supplement that the Irish studied is marketed in England as ReMind [remind.eu] and in the United States as MemoryHealth. [memoryhealth.com]
Both supplements come from MacuHealth. The lead author of the study this post is about, plus another co-author, have ties to MacuHealth. For this reason, we have taken the liberty of classifying this research as 'sponsored'.
Supplementation reduced the number of mistakes the subjects made. This implies that the working memory of the subjects improved.
"These findings illustrate the importance of nutritional enrichment in improving cognition and enabling older adults to continue to function independently, and highlight how a combination of omega-3 fatty acids and xanthophyll carotenoids may prove beneficial in reducing cognitive decline and/or delaying Alzheimer's disease onset in later life", write the Irish.
